useful Improvements in Amplifying-Ilorns,

of which the following is a specification.

The objects of'this invention are. to provide an amplifying; hornflaring upon curved lines which shall be'composed of transversesections, each comprising a seamless or circumferentially integral band;to thus reduce the number of.parts or 'pieces in such a horn and securet'ewer seams; to enable a horn flaring on curved lines-to be ble; toprovide interchangeable sections for the small end of the horn so thatthe main body of the horn can be used' for difl'erent talking machines,and t0 secure-other advantages and results as may be brought out in thefollowing description.

' ieferring to the accompanying drawings,

in which like numerals of reference indicatecorresponding parts in eachof the several is a side elevation, partly in central vertical section,of a horn of my improved construction; Fig. 2 is a plan of .the same;Fig. 3 is a view similar to Fig. 1

except that the horn sections are shown detachably united, and Fig. 4shows a small end section adapted. to replace the one shown in Fig. 3for certain kinds of talking machines.

It will be understood that horns of the type to which mypresentinvention relates, that is, horns which flare. upon curvedliues,- morning-glory or flower horns as they are. commonlycalled,-ha\-'e heretofore been made of a large nmuber of longitudinalsections or strips, since it obviously was impossible to form of one oror horn section which flared upon other than strai 'ht lines. The resultof this construction nas been a multiplicity-of seams or joints in thehorn, which not only n'iarred its appearance but also intertcwed withits acoustic properties.

My purpose is to do away with all these objectionable features andprovide a horn flaring upon curved lines which shall have a minimumnumber of joints or seams. To this end the horn is constructed ofa'longitudinal series of transverse sections each of which is composedof a seamless integral band which has been pressed, stamped orSpecification of Letters Patent.

its proper fol-unto wit, a flarin shapeiu which the lateral lines arecurve in Figs. 1 and lot the drawings I have shown such sections 2 3, 4,etc., which are connected at their adjacent edges, as at. t l, byreaming or any other means known to the art to att'ord a permanentconnection. A horn is. thus provided which flares co'ntinuously oncurved lines and yet. is composed of a small number of pieces and has astill less number of seams. 1 7 Obviously, the. degree of curvature ofthe sides of the horn maybe varied, and the length of the sectionschanged at will, with out departing from he spirit and scope of theinvention.- y y In Fig. dot the drawings I have shown sections 6, 7 8,etc. of the horn detachably connected, as by screwing together at theiradjacent ends, as at 12, although any other appropriate means ofcoupling together couldbe employed if desired. Furthermore,

the larger end of each section screws inside of the smaller end of thenext adjacentsection, as shown in the drawings, so that when thesections are screwed apart the horn will collapse andncst its sectionsone within an-,'

other. I 7

One advantage. of the construction inl ig. 3, is that in manufacturing,(litterent small-end sections may be employed with the rest of thebornto accommodate it to dilter'ent conditions, makes of machines, andso forth. For instance, the end.section 9 shown in Fig. 3 isadapted tothe use of the. horn upon phonographs, while in Fig. i I have shownanother end section 10 which is adapted to replace the end section 9 andenable the horn to be applied to gramophones. It will thus be nnderstomlthat. by having a judicious assm'tmentot' small-end sections,thenumber'of horn bodies carried in stock could be greatlyreduced.sincethey would be available foiydifferent purposes.

Having thus described the invention what shown The hereindescribed horn,composed of a plurality oftransverse sections adapted .to be connectedend to end, each section comprising a seamless band and-having its wallsJOHN H. R'OONGER.
